The microphone capsule photo and information thread

[LevinGuitar]

SE2200T capsule. Surely used in other SE microphones as well, and I wonder if not by other brands. The mylar seems a bit different (thinner sputtering?) than the average chinese k67

Many thanks to @LevinGuitar and all the other contributors .

Yes, the backplate construction is also different to other 32mm. SE has less HF boost, but extends much higher in HF than most k67.

Anyone have photos of the capsule in PreSonus PM-2? A Mix review claims it's a center-terminated SDC; something I didn't think existed. Of course, at 3/4" it's more 'MDC'.

Despite the photo on their website, they are apparently no longer available (no listing on their website.

Could be similar (or the same?) to the first MAudio Pulsar.
Please ignore the green ERO cap, I tried them (the other one is under the pcb) for output but lost some low end because the original SMT caps were even larger.

The PX1 mic looks to me the same as the old Sterling ST51 and company.

Blue Mouse - Made in USA, but internal PCBs and components all have 'made in latvia' markings. Suspect between 2005-2009. Transformer version.

Advanced Audio AK12, obviously a CK12 variant. Heavy sputtering makes it nearly impossible to see the backplate hole pattern.

Why do you think that's a center-terminated capsule? From the back it look much like the Primo EM-21, but with a gold diaphragm.

Vanguard Audio. Capsule from the 1st gen V44S. They've spoken about how it's an in house design, I can't comment on that, but obviously at the least inspired by a CK12. Backplates are obviously not isolated. Transformerless FET, stereo mic in this case. I have to say I was really impressed with the sound and build quality when I got it, it pretty much stays permanently on a stand in my studio. Really nice on vocals.

I haven't said so nor I do think that, as well I don't believe the FR curve of that review.
I can't see any reflection on the diaphragm so it could be not gold sputtered neither.
Don't know Primo capsule, so not sure if it's the same

Edit: I googled EM21 capsule and even it don't look the same, it seem to have same weird ring on unknown (to me) material as the MAudio capsule.

It's just a ring of foam.

They're just snapshots from my repair adventure, so they are not the best but may be useful for someone. Just for reference: each backplate is 20mm in diameter, with a thickness of 1mm, while the other part of the backplate is ~0,5mm thick. There's mesh in between to keep debris out. The distance from the membrane to the backplate is set via a spacer with a thickness of ~0,03mm (see pictures).

B&K / DPA 4006 backplate.
Quite big distance between membrane and backplate.

Anyone know anything about this one? Looks like a Chinese knockoff of an Oktava 219/319 capsule. I grabbed a pair on some site, some years back, directly from China; a few years before the knockoff 102 and 103 style bodies started to appear.

They sound great! Super-duper bright without any harshness whatsoever! Problem is, from the very beginning, they slowly become super-duper hissy 5-minutes after they’re powered-up!
